T at whom it mriy concern:

Be it known that we, ROBERT 3. GOOD and JULIUS H. SOHLAFLY, citizens ofthe United States, residing at Canton, in the county of Stark and Stateof Ohio, have invented certain new and useful Improvements in Can-Forming Machines; and we do hereby declare that the following is a full,clear, and exact description ofthe same, reference being had to to theannexed drawings, making a part of this specification, and to thefigures of reference marked thereon, in which-- Figure 1 is aperspective view.

' The present invention has relation to can be forming machinesespecially designed to form the cylindrical portions of the can-body;and it consists in the different parts and combina tion of partshereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the base, which is formed ofsufficient 7o size to properly support the various parts of the machine,from which base extends the vertical part or web 2. The front or forwardportion of the web 2 is provided with a suitable bearing 3, which isformed of sufficient length to support the power -shaft 4, saidpower-shaft being properly journaled at one or both of its extreme endsby suitable pillars 5, havingsuitable bearings 6. Upon the power-shaft tis securely attached inany convenient and well-known manner thepowerwheel 7,which may be either a belt-wheel or gear-wheel, as desired.The mandrel 8 is securely attached in any convenient and wellknownmanner to the vertical part of the web 2 or its equivalent and isextended any desired length toward the rear of the machine proper, themandrel, however, being of such a length that when the. variousoperations have been performed upon the blanks from which the can-bodiesare made theywill be moved off from the end of the mandrel and allowedto drop therefrom.

To the upper portion of the center web 2 are connected the side platesor housings 9, 5 which carry the feed-rollers 10 and 11 and theforming-rollers l2 and 13,'said feed-rollers and forming-rollers beingdriven by means of suitable gear-wheels 14:, which gear-wheels are soarranged that the upper and lower Ice lower rollers in both instancesrotated in the same direction, and in order to accomplish this anintermediate gear-wheel or idler 15 is employed.

The feed-rollers 10 and 11 are for the simple purpose of feeding theblanks from which the can-bodies are formed to the forming-rollers l2and 13. The forming-rollers 12 and 13 are provided with the beads 16 andthe grooves 17, the beads 16 being located upon the upper roller at oneend and the lower roller at the opposite end and the grooves 17 locateddirectly opposite the beads 16, so that the seamfianges will belocated'upon opposite sides of the bodies from which the cans areformed, this being necessary to bring the flanges in proper position tobe hooked together at the time the blank from which the can-bodies areto be formed are brought into cylindrical form.

For the purpose of feeding the blanks to the feed and forming rollerscarrying-chains 18 are provided, which carrying-chains are locatedaround the sprocket-Wheels 19 at their outer ends, and at their innerends they are located around the lower forming-roller l3, suitablegrooves being formed to receive or make room for the carrying-chainsbetween the feeding and forming rollers and at the same time bring theinner upper portions of the chains out of the Way and out of contactwith the can-bodies blanks. After the canbody blanks have passed throughthe forming-rollers l2 and 13 they are brought directly over themandrel, as illustrated in Fig. 2, and also directly under the forminghead or die 20, which forming head or die is pivotally connected to thevibrating arm 21, said arm being supported by the standards 22.

For the purpose of causing the forming head or die 20 to move up anddown in a true vertical plane said die is extended upward above the arm21, and to the upper end thereof are attached the rods 23, which rodsextend rearward and are pivotally connected at their rear ends tosuitable supports 24. V

For the purpose of imparting vibrating movement to the arm 21, carryingthe forming head or die 20, the cam 25 is located upon the power-shaft4, which is provided with the groove 26, formed in the side face of saidcam, and in which groove is located an antifrictionroller 27 or itsequivalent, which roller is mounted upon a pin secured to the rock-arm28, said rock-arm extending rearward and is secured to the cross-shaft29, and upon which cross-shaft 29is also located a short rock-arm 30, towhich rock-arm is connected the bottom or lower end of theconnecting-rod 31, the top or upper end of which is adjustably attachedto the vibrating arm 21.

It will be understood that the downthrow of the cam 29 will carry therock-arm 28 downward at its swinging or cam end, and thereby rock theshaft 29, which in turn moves the free end of the rock-arm 3O downward,carrying with it the connecting-rod 31, bringing the vibrating armdownward. As the vibrating arm 21 moves downward the forming head or die20 when brought to its lower point will be brought against the upperface of the canbody blank, The concave face of the die 20 correspondingin curvature with the curvature of the mandrel 8, or substantially so,as the forming head or die moves downward or toward the mandrel 8 thecan-body will be bent around the upper portion of the mandrel, thisfeature being illustrated in Fig. 7, except that the can-body has beenbent entirely around the mandrel.

It will be understood-that the downward movement of the forming head ordie simply acts upon the upper portion of the mandrel and does notcomplete the cylindrical formation of the body, but brings the can-bodyinto such a position that it can be operated on to form a perfectcylinder by the devices hereinafter described.

Upon the power-shaft 4 are securely attached the cams 32 and 32, whichcams are for the purpose of rocking the seam-locking rock-arms 33, whichseam-locking rock-arms are independently mounted upon the short stud 34,which short stud is located directly below the mandrel 8, as illustratedin' Figs. 2 and 7, and is securely connected or formed integral withsome integral part of the frame proper. Upon the seam-locking rock-arms33 are adjustably attached the seam-locking plates 35 and 36. After theforming head or die 20 has been brought down upon thecanbody saidcan-body will be in a position to be acted upon by the oscillatingmovement of :the seam-locking plates 35 and 36.

It will be understood that the upward throw of the cams 32 and 32 willmove the seamlocking plates 35 and 36 toward each other, the cams beingso arranged that the movement of the seam-locking plates 35 and 36 willbring the outer hooked edge over the innerhooked edge of the can-body,this feature being best illustrated in Figs. 3, 4, and 5. After theseam-locking plates 35 and 36 have been brought to their highest point'and the hooked edges of the can-body brought together, so as to beproperly locked, they are permitted to recede, and for the purpose ofproducing a quick and positive action the springs 37 are provided, thelower ends of which are secured to some fixed object and. their upperends secured to the bottom or under sides of the seam-locking rock-arms33.

For the purpose of reducing the friction between the faces of the cams32 and 32 and the ends of the seam-locking rock-arms said seam-lockingrock-arms should be provided with the antifriction-rollers 38, thisfeature, however, being more of a matter of judgment than invention, asit will be understood that the sameobject can be accomplished withoutthe antifriction-rollers 38.

The hooked edges of the can-bod y are simply loosely locked together,or, in other words, an open seam is produced, this being necessary inorder that the hooked edges of the canbody may be properly coated withacid and solder.

After the operation just above described has been performed the can-bodyin its cylindrical form is moved along the mandrel by the deviceshereinafter described, the seam coming in contact with the rotaryacid-brush 39, (illustrated in Fig. 1,) which rotary acidbrush receivesits supply from the acid-receptacle 40, the bottom or lower portion ofthe brush being submerged in the acid. Rotary motion is imparted to thebrush in any convenient and well-known manner; but as illustrated it isimparted by means of the drivebelts 41 and 42, the drive-belt 42 leadingfrom the power-shaft to the double pulley 43 and the belt 41 leadingfrom the double pulley 43 to the pulley 44. It will, however,

' be understood that the manner of imparting rotary motion is simplymechanical and many ways may be employed to impart rotary m0- tion tothe acid-brush 39. Between the acidbrush and the delivery end of themandrel is located the solder-receptacle'45, (best illustrated in Figs.10 and 11,) and for the purpose of giving to each can-body seam twodistinct solder baths or submersious the solder-receptacle is formed ofsuch a length that two properly-spaced cans may be located between theends of the solder receptacle 45, this feature being best illustrated inFig. 10.

It will be understood that at the time the seams of the can-bodies aresubmerged or dipped into the solder the hooked edges are only looselylocked together, by which arrangement the necessary amount of solder isallowed to enter between and upon the hooked edges of the can-bodies.

Within the receptacle 45 is located the reciprocating trough orsolder-lifting device 46, to

which are attached the bars 47', which bars are inclined upward andoutward from the trough 46 and thence downward upon the outer sides ofthe solder-receptacle 45, this construction being best illustrated inFigs. 10 and 11. The downward ends of the bars 47 are provided with theright-angled portions 48, through which right-angled portions arelocated the adjustable contact-bolts 49, said contact-bolts beingconnected in such a manner that the arms 47, together with the trough46, will be elevated, as hereinafter described.

To the vibrating arm 21 is attached the connecting-rod 50, the bottom orlower end of 54, formed in the reciprocating bars 55, said reciprocatingbars being supported upon suitable rests 56 or their equivalents. Thereciprocating bars are provided with the inclines 57, saidinclines beinglocated under solder the seam of the can.

the adjustable bolts 49 and in such relation to each other that when thereciprocating bars 55 are moved in one direction the bolts 49,

together with the arms 47 and the trough 46,

will be elevated, and when moved in the opposite direction said partswill move downward by gravitation. It will be understood that thereciprocating movementimparted to the connecting-rod 50 will impart ahorizontal reciprocating movement to the bars: 55 by means of therock-arm 51 and the arm 53.

When the trough 46 is lowered or submerged in the solder contained inthe solderreceptacle 45, the trough 46 will be filled with solder, whichis carried upward above the solder-line in the solder-receptacle, andthe loosely-hooked. edges of the can-body will be submerged in thesolder contained in the trough 46, by which arrangement a sufficientamount of solder is placed upon the looselyhooked edges of thecan-bodies to properly After the seams of the can-bodies have beenproperly coated with solder they are moved upon the mandrel 8 until theycome directly over the seamclosing head58, which seam-closing head isgiven a reciprocating movement by means of the connecting-bar 59, whichconnecting-bar is secured at its upper end by means of the Years and thecross belt or pin 61 and at its bottom or lower end by means of the ears62 and the cross-head 63, the cars 62 being formed integral or securelyattached to the rock-shaft 29, this construction being best illustratedin. Figs. 12 and 15.

It will understood that in order to properly close the seam the soldershould be heated at the time the seam is closed, and in order to preventthe solder from hardening or becoming too cool for practically closingthe seam the seam-closing head 28 is heated by means of suitableopenings 64, in which open ings gas is burned, thereby keeping theseamclosing head hot.

It will be understood that gas should be conveyed to the seam -closinghead 58. by means of a flexible tube, such as 65, inasmuch as areciprocating movement is imparted to the seam-closing head.

It will be understood that the thrust of the seam-closing head 58 willhave a tendency to move or elevate the mandrel 8, and in order toprevent its upward movement the crossbar 22 is' provided, whichcross-bar is secured in any convenient and well-known manner to thestandards 22. It will also be understood that the can-bodies must moveunder the cross-bar 22, and the mandrel is so adjusted that its normalposition will be slightly below the cross-head, so as to providesufficient space between the top of the mandrel and the bottom of thecross-bar to allow the can-bodies to pass unobstructed as they are movedalong the mandrel.

After the seams of the cans have been properly closed they are movedalong the mandrel 8 and pass over the solder-distributors 66,

which distributers place the solderin proper position and at the sametime leave the seam in proper condition with reference to the solderthereof. In order to accomplish this result, it is necessary to keep thesolder in a heated state, the heat being of such a degree that it willnot leave the seam of the can, but be soft enough to allow the same tobe properly distributed. In order to bring about this result, thegas-burners, such as 67, are provided and held in fixed position in anyconvenient and well-known manner. They are illustrated being supportedupon the pipe 68. After the cans have been moved along the mandrel untilthey have fully passed the solder-distributors they are completed, andno further operation is performed upon the cylindrical can bodies, butare moved off the mandrel properly formed into cylinders and their seamsproperly finished.

Adjacent to the mandrel 8 and-below the horizontal center thereof arelocated the reciprocating rods 69 and 70, which reciprocating rods aresupported in suitable bearings, such as 71 and 72; but it will beunderstood that other bearings may be provided, as the reciprocatingrods should be held in parallelism With the mandrel 8.

For the purpose of imparting a reciprocating movement to the rods 69 andthe cam 73 is mounted upon the power-shaft 4, which cam is provided withthe groove 74, and in which groove is located a suitable cross-pin 75,which cross-pin is connected to the vibrating arm 76, said vibrating armbeing pivotally attached to the bearing 77, said bearing being held infixed position to the base of the machine or to the floor upon which themachine proper stands. To the upper end of the vibrating arm 76 ispivotally attached the connecting-rod 78, the opposite end of saidconnecting-rod being pivotally attached to the bottom or lower end ofthe rock-arm 79, which rock-arm extends below and above the stud 80,which stud is fixed to some part of the machine-frame.

It will be understood that by the rotation of thepower-shaft areciprocating movement will be imparted to the connecting-rod 78 bymeans of the vibrating arms 76 and the cam 75, which in turn imparts arocking movement to the arms 79. The top or upper-end of the rock-arms79 is provided with the yoke 81, which yoke carries grippers 82', soadjusted that a true reciprocating movement can be imparted to the rods69 and 70 by the rocking movement of the rock-arms 79.

It will be understood that the can-bodies should be moved upon themandrel at certain intervals, and during the intervals of the movementof the can-bodies upon the mandrel the various devices performoperations, such as looking the seams, soldering the loosely-lockededges of the seams, and closing the seam of each can-body. The devicesperforming these various operations should be so timed that they willnot be in contact with the can-bodies or with the seams of thecan-bodies at any time during the various steps of the diiferentoperations to be performed to complete the seam, and the various cansand other devices are so arranged with reference to the devices formoving the can-bodies that when the devices for moving the can-bodiesare in operation the devices.

for performing the different steps to complete the seam are out ofcontact or operative en= gagement with the seams of the can-bodies. Inorder to accomplish this result, it is nec essary that the blanks fromwhich the canbodies are formed should be spaced from 'each other, so asto give time for the cancarrying devices to move into position to give Tthe can-bodies the proper movement upon the spaced relation withreference to each other to have the various operations performed uponthe seams of the can-bodies and at the same time allow the can-bodies tobe moved longitudinally upon the mandrel at the time the various devicesemployed in performing the different steps upon the seams of the cansare out of con-tact or have receded from the can-bodies, thecarrying-chains 18 are each provided with the push-lugs 83, saidpushlugs being so spaced upon the carrying-chains that proper space isprovided between all of 'the can-bodies to allow the various devicesperforming operations upon the can-bodies,

either in bending the can-bodies, forming the seam, and carrying thecans, to be brought into action at such times that one action will notinterfere with another.

It will be understood that the solder-receptacle 45 should be heated, soas to properly melt the solder and keep it in such a condition that itcan be applied to the loosely-locked i edges of the can-body, and inorder to bring this result a gas-burner, such as 84, is employed and isso located that it will properly heat the solder-receptacle. No detaildescription of the gas-burner 84 is here given, owing to the fact thatvarious styles and kinds of gas-burners may be employed withoutdeparting from the nature of the present invention.

To, the power-shaft 4 is attached the cam 85, to which cam is attachedthe connectingrod 86 by means of the usual connecting-head 87. Theconnecting-rod 86 extends rearward, and its rear end is, connected tothe adjustable head 88, which adjustable head is connected to thevibrating arm 89, said arm being provided with the rocking head 90, towhich rocking head is attached the arm 91, the

rocking head being mounted upon the bar 92, which bar is secured infixed position to the rearward-extending frame 93 or its equivalent.

To the arm 91 is pivotally connected the bottom or lower end of theconnecting-rod 94C, to

the top or upper end of which is pivotally attached the oscillating head95, said oscillating head being so attached that the reciprocating rodcan move the oscillating head, but at the same time cause the rod 70 torock with the oscillations of the head 95. This result may beaccomplished by means of the longitudinal groove 96, formed in the rod70, and a lug formed in the eye of the oscillating head 95. Totlie rod70 are securely attached the can-carrying dogs 97 and 98, and upon therod 69 are also securely attached the cancarrying dogs 99, saidcan-carrying dogs 97 and 98 being substantially of the form shown andare practically of the same constructionthat is to say, the dogsopposite each other or upon opposite sides of the mandrel S are alike.

It will be understood that by providing means for rocking thereciprocating bars 69 and 70 the various dogs for carrying the canbodiescan be moved to and from the mandrel 8 by means of the cam and theintermediate connection between said cam 85 and the oscillating head 95.i It will be understood that the upward movement of the connecting-rod94E will move the various can-carrying dogs toward the mandrel, all ofthe dogs being operated simultaneously by means of the connecting-links100, which links are connected to the arms 101 and 102, said arms beingextended from the heads 103 and 104:.

In order to' give a simultaneous inward movement to all of thecan-carrying dogs upon both of the reciprocating rods 69 and '70, thearms 101 are located or extended upward from the reciprocating bar 70and down- Ward from the reciprocating bar 69.

For the purpose of insuring the proper engagement of the variouscan-carrying dogs.

with the can-bodies the mandrel 8 is provided with the grooves 105, andinto which grooves the inner ends of the various dogs enter, so thatthey will fully pass the ends of the canbodies, and thereby prevent anydanger of the dogs from slipping or passing the end of the can-bodies assaid can-bodies are moved upon the mandrel with the simultaneousmovement of the can-carrying dogs.

For the purpose of allowing the can-carrying dogs to be at the properplace with reference to the location of the can-bodies at the time saidcan-carrying dogs are moved inward, so as to engage in operative contactwith the can-bodies, some of said dogs may be provided with the lateralarms 106, this feature being necessary for the purpose of allowing thereciprocating bars 69 and 70 to receive their full reciprocatingmovement, carrying with them the Various can-carryin g dogs, withoutinterfering with any fixed object, such as the oscillating head 95 orthe different bearings for said reciprocating rods 69 and 7 0.

For the purpose of supporting the rear ends of the reciprocating rods 69and 70 a standard or support 107 should be provided, which is held inrigid position by suitable braces, such as 108, or their equivalents.

The working face of the cam 32 is so formed that it will give to theseam-locking plate 35 a movement such as to bring the'can-body in theposition illustrated in Fig. 3. This is the first dwell of thelocking-plate 35. The face of the cam 32 is so formed that thelockingplate 36 will move into action and bring the can-body having thehooked edge into position illustrated in Fig. 4, after which the cam 32moves the locking-plate 35 so as to hook the edge over the flange edgeof the can-body, as illustrated in Fig. 5. This is the second dwell ofthe locking-plate 35.

For the purpose of imparting a rotary movement to the feed-rollers thepower-shaft 4 is provided with a sprocket-wheel 4:, around which extendsthe sprocket-chain 5 and around the sprocket-Wheel 6", which is fixed toone of the feed-rollers or one of the forming-rollers, as desired. thismanner of imparting rotary motion; but it will be understood that otherforms of gear maybe employed without departing from the nature of ourinvention.

g The solder-distributors 66 are journaled to the upper ends of thepivoted arms 66 and the distributers held in contact with the canbodiesby means of springs 67 said springs being secured at their bottom endsto the plate 68, and to which plate is connected or formed integraltherewith the post 69, said post being for the purpose of providingmeans for pivotally attaching the solder-distributing arms 66. Theburners 67 are arranged upon opposite sides of the distributers 66 andare so arranged that they will keep the distributors hot, so that theywill properly act upon the solder as the can-bodies pass thedistributers.

For the purpose of preventing the solderdistributers from coming incontact with the seams of the can-bodies during the time they are atrest upon the mandrel the distributors 66 are so spaced that they willbe out of contact with said solderdistributers when at rest and incontact only at the time the canbodies are moved along and upon themandrel.
